HighPower LED's
High-power LEDs are highly effective and particularly bright light-emitting diodes. Constant current is conducted through a semiconductor, more specifically through semiconducting crystals, which causes electrons to vibrate and thus to light. According to this principle, called electroluminescence, high-performance LEDs create up to 100 lumen light per watt. For example, a High Power LED with 5 watt power generates up to 500 lumen brightness. High-power LEDs consume a larger amount of electricity and need a higher current than conventional LEDs, for example 700mA. They transform the energy supplied into light resp. photons and thereby produce extremely intensive light, but thermal energy as well. That in turn makes cooling neccessary. For that reason, at the High Power LED’s backside there is a metall PCB as cooling option and for heat dissipation. Frequently the whole housing of a high-performance light diode serves as cooling element.
Advantages of High Power light-emitting diodes
The great advantage of high-performance light diodes resides in their high luminous efficacy with minimum dimensions. However, luminous intensity and efficiency are affected by the junction temperature. That is the temperature within the light-emitting diode at the transition from positively conducting to negatively conducting material. A junction temperature, that is too high, would reduce the diode‘s light output as well as its lifetime. In order to ensure the desired luminous efficacy and an optimun mode of action, the junction temperature should always lie within the pre-set values.
Besides their intensity of light Highpower LEDs deliver more impressive benefits, which make them versatile. Thanks to the great light yield and the comparatively compact design high power diodes are predestined for use as model construction light. Furthermore, they are shock and vibration resistant, which matters in terms of installation in model vehicles and in measurement technology. Their long lifetime of up to 30.000 hours corresponds to approximately three years light duration. High Power LEDs work highly failsafe, thus maintenance and replacement works remain within limits. Therefore they are attractive for many fields of application.
From aquarium lighting to RC-model making – do it easily yourself with Highpower LEDs
No matter you want to built a torch, LED aquarium lights or LED grow light by yourself or you want to replace a defect chip in a LED flood light, High Power diodes are the first choice. High-performance LEDs in red with appropriate optical wavelength of 600-700nm support photosynthesis and plant growth. Highpower LEDs in RGB colours are well suited for illumination of model construction, as well as for model boats, model trains or for lighting of remote-controlled model cars. In addition High Power LEDs are used in industry and research as illumination for prototype construction. Herein LEDs are employed not only in the usual colours, but also in infrared . Ultrared Highpower LEDs are used, for example, in night vision devices. Not at least high-performance LEDs with 1W, 3W or 5W serve as spare part for LED floodlights. With their help hobbyists are able to repair LED flood lights and LED spot lights by replacing single defect LED chips.
Small dimensions but true muscle men – high performance light diodes are a firmly established element of everyday life and their fields of application will continuously expand.
